Now, a source close to Martinez is saying "Yes, it's a romance," according to UsMagazine.

Paris-born Martinez is no stranger to dating gorgeous woman in long-term relationships. After four years of dating Australian singer Kylie Minogue, the two called it quits in February 2007 after reports surfaced that the sexy actor was seen romancing younger women in LA while she was in Britain.

As for Halle, she's been through plenty of dating drama ... aside from her recent separation from model Gabriel Aubry, the father of 2-year-old Nahla. In April, their split became official after nearly five years together.

Prior to her relationship with Aubry, the Oscar winner had two failed marriages. Her first marriage was to former baseball player David Justice which ended in 1997, and her marriage to musician Eric Benet ended in January 2005.

Hopefully these two hotties have put their relationship drama behind them and are ready to start fresh. Judging by these steamy pictures of them off-screen, we can't wait to see the sparks fly in their upcoming film, Dark Tide. The movie is centered around a diving instructor who returns to deep waters after almost being killed by a Great White shark.

There are plenty of scenes with Halle in a two-piece. No wonder Olivier has fallen hard!
